In animal tissues, a family of enzymes termed cytochromes P450s are involved in fatty acid oxidation, hydroxylating with high specificity at the energetically unfavorable terminal (omega) or omega-1 carbons. Hydroxy fatty acids primarily come from consumption of plant products (vegetables or fruits) or from cows milk. Omega hydroxy fatty acids are found in the structure of suberin, a lipid polyester present in plant cell walls, and of cutin, a lipid polyester which is a component of the plant cuticle. These apoplastic structures are important plant-environment interfaces which act as barriers limiting water and nutrient loss and protecting plants from radiation and pathogens.
